Polyurethane foam injection is not a permanent solution for structural loads or foundation settlement. While it is an effective tool for non-structural applications, such as filling minor voids or leveling interior slabs, sidewalks, and driveways, it lacks the engineered capacity to support a building’s foundation long-term.
For a permanent solution, we recommend Helical Piers or Push Piers. Unlike foam, which may degrade or fail to address deep-seated soil movement, our steel pier systems provide permanent underpinning by transferring the structural weight past unstable surface soils to competent bearing strata or bedrock.
Why Steel Piers Outperform Polyurethane Foam:
- Permanence: Steel piers are engineered to provide a lifetime of stability, whereas foam is considered a temporary lift for non-structural slabs.
- Load-Bearing Capacity: Our helical pier systems can support loads exceeding 100 tons per pier, while polyurethane foam is typically limited to lifting loads under 20 tons.
- Soil Adaptability: In expansive clay or high-moisture soils, foam often fails to reach the stable strata needed to prevent future movement. Our advanced earth anchoring systems bypass these active soil zones entirely.
- Engineering Standards: We utilize ICC and ISO Certified products backed by ICC-ES documentation, ensuring your repair meets the highest building code standards.
Because every project has unique soil and structural requirements, we always recommend you consult a structural engineer or our Engineering Excellence and Design Support team for project-specific guidance. Installations must comply with applicable building codes and ICC-ES acceptance criteria (AC358). Please contact us to request a custom quote for your stabilization needs.
